Text solutionVerified

After closing the switch circuit current is given as

i = \frac{9}{9} = 1 A

Potential difference across the capacitors are given as

V_{1} = 3 \times 1 = 3 V and V_{2} = 6 \times 1 = 6 V q_{1} = 3 \times 3 = 9 μ C and q_{2} = 6 \times 6 = 36 μ C

Charge at junction

x

on the two plates of capacitors is

Δ q = - 9 + 36 = 27 μ C

Initially when the switch was open charge at junction

x

at the two plates of capacitors was zero so the charge which is there on the two plates after closing the switch is flown through the switch from

y

x

when it is closed.
